Branch meeting, open to all. Light refreshments from 18:00, talk from 18:30.
Richard Feynman was asked what single idea would be the best help to revive science after a new Dark Age, and the message he chose to pass on was just "Everything is made of Atoms."
From the speculations of Greek philosophers, through the kinetic theory of gases and the structure of solids, to the early applications of quantum mechanics, the concept of the atom and its modelling have been a significant thread in the development of modern science, in particular for Physics and Chemistry.
Some of that story is explored in this talk, which tries to look behind the usually simplistic treatments of the text-books at what really happened.
